Error codeF31
ApplianceRange
The oven sensor circuit looks shorted to the control when F31 appears. Frigidaire’s range guide titles the code Shorted Probe, and it belongs to current ranges and wall ovens with an electronic oven control (EOC).
Checks written for technicians
Read the sensor’s resistance at room temperature.
Replace the RTD sensor probe if the reading falls below the stated limit.
Test the harness between the control and the probe connector for a short.
What the range guide says about timing
A unit installed during the past 30 days goes back to its installer. Beyond 30 days the guide points to a service visit.
Frigidaire ovens showing F31 in San Francisco can be booked through (415) 319-6371. Have the code, the model number and anything you have already tried ready. The Frigidaire range repair page adds detail.
Model compatibility: Frigidaire reuses codes across series and model years, so F31 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F31 is a shorted probe connection on the oven sensor circuit.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
